This application is a continuation of U.S. Application No. 17/872,398, filed Jul. 25, 2022, which in turn claims priority under 35 USC 119 from Japanese Patent Application No. 2021-151951, filed on Sep. 17, 2021. The disclosure of each of the priority applications is hereby incorporated by reference herein.

BACKGROUND Technical Field

The present disclosure relates to a vehicular display control device, a vehicular display system, a vehicle, a display method, and a non-transitory computer-readable medium storing a program.

Related Art

Japanese Patent Application Laid-Open (JP-A) No. 2021-75157 discloses a configuration in which operation switches are provided on the left and right of a steering wheel. In JP-A No. 2021-75157, images of the operation switches are displayed on a display screen and different functions are allocated to the respective operation switches.

In JP-A No. 2021-75157, images of both the left and right operation switches (operation regions) are displayed on the display screen, and so a large display region needs to be secured. However, if an image of the operation switches on one side alone were to be displayed, it would be difficult to discern at a glance which operation switches were being displayed, and so there is room for improvement from the perspective of improving occupant usability.

SUMMARY

The present disclosure provides a vehicular display control device, a vehicular display system, a vehicle, a display method, and a non-transitory computer-readable medium storing a program that enable occupant usability to be improved in configurations capable of displaying an image of an operation region.

A first aspect of the present disclosure is a vehicular display control device including: memory; and a processor coupled to the memory, wherein the processor is configured to: detect when a right-side operation region provided on a right side of a steering wheel has been operated; detect when a left-side operation region provided on a left side of the steering wheel has been operated; in a case in which operation of the right-side operation region has been detected, display a right-side image corresponding to the right-side operation region in a right-side area of a display region set in front of a driving seat; and in a case in which operation of the left-side operation region has been detected, display a left-side image corresponding to the left-side operation region in a left-side area of the display region.

In the vehicular display control device according to the first aspect, the right-side image corresponding to the right-side operation region is displayed in the right-side area of the display region set in front of the driving seat in cases the right-side operation region provided on the right side of the steering wheel has been operated. Similarly, the left-side image corresponding to the left-side operation region is displayed in the left-side area of the display region in cases the left-side operation region provided on the left side of the steering wheel has been operated. This enables a wide area of the display region to be secured compared to cases in which both the right-side image and the left-side image are always displayed on the display region.

Moreover, since the right-side image is displayed in the right-side area of the display region whereas the left-side image is displayed in the left-side area of the display region, an occupant can intuitively ascertain which operation region the displayed image corresponds to out of the right-side operation region or the left-side operation region. Note that here, the “right side” indicates the right side in a state facing a direction of progress of the vehicle, and the “left side” indicates the left side in a state facing the direction of progress of the vehicle.

In a second aspect of the present disclosure, in the first aspect, the processor may be configured to: always display a central image indicating a vehicle state in a central area of the display region; and display the right-side image further toward the right side than the central image, and display the left-side image further toward the left side than the central image.

In the vehicular display control device according to the second aspect, the occupant may even more easily ascertain which operation region the displayed image corresponds to out of the right-side operation region or the left-side operation region.

In a third aspect of the present disclosure, in the second aspect, the processor may be configured to move the central image toward the left side when displaying the right-side image, and move the central image toward the right side when displaying the left-side image.

In the vehicular display control device according to the third aspect, since the central image is moved, the corresponding right-side image or left-side image may be displayed in a large size, even in cases in which the display region is relatively small.

In a fourth aspect of the present disclosure, in any one of the above aspects, the processor may be configured to: display the right-side image as an animation so as to move from a lower-right side end of the display region; and display the left-side image as an animation so as to move from a lower-left side end of the display region.

In the vehicular display control device according to the fourth aspect, since the display is an animation, the occupant may intuitively ascertain that the image (the right-side image or left-side image) displayed on the display region corresponds to an operation region (the left-side operation region or right-side operation region) provided on the steering wheel.

In a fifth aspect of the present disclosure, in any one of the above aspects, the processor may be configured to: display information relating to driving assistance in the right-side image and display information relating to onboard equipment in the left-side image; and display the right-side image in cases in which operation of both the right-side operation region and the left-side operation region has been detected.

In the vehicular display control device according to the fifth aspect, the right-side image including the driving assistance-related information is displayed in cases in which operation of both the right-side operation region and the left-side operation region has been detected. This enables the occupant to prioritize checking information relating to driving assistance.

In a sixth aspect of the present disclosure, in any one of the above aspects, the processor nay be configured to: display a right-side suggestion image that is selectable using the right-side operation region in the right-side area of the display region; and display a left-side suggestion image that is selectable using the left-side operation region in the left-side area of the display region.

In the vehicular display control device according to the sixth aspect, in cases in which a suggestion from a navigation system or the like is displayed using the right-side suggestion image or the left-side suggestion image, this suggestion is displayed at a position corresponding to the pertinent operation region, thereby enabling the occupant to intuitively ascertain the position of the operation region they should operate.

In a seventh aspect of the present disclosure, in any one of the above aspects, the processor may be configured to display the right-side image and the left-side image in the display region set on a windshield glass using a head-up display device installed to a vehicle.

In the vehicular display control device according to the seventh aspect, the contents of the corresponding right-side image or left-side image can be checked in a state in which the occupant is directing their gaze toward the front while driving.

An eighth aspect of the present disclosure is a vehicular display system including: the vehicular display control device of any one of above aspects; and an image display device configured to perform display in the display region.

A ninth aspect of the present disclosure is a vehicle including the vehicular display system of the eighth aspect.

A tenth aspect of the present disclosure is a display method including: detecting when a right-side operation region provided on a right side of a steering wheel has been operated; detecting when a left-side operation region provided on a left side of the steering wheel has been operated; in a case in which operation of the right-side operation region has been detected, display a right-side image corresponding to the right-side operation region in a right-side area of a display region set in front of a driving seat; and in a case in which operation of the left-side operation region has been detected, display a left-side image corresponding to the left-side operation region in a left-side area of the display region.

An eleventh aspect of the present disclosure is a non-transitory computer-readable medium storing a program for causing a computer to execute processing including: detecting when a right-side operation region provided on a right side of a steering wheel has been operated; detecting when a left-side operation region provided on a left side of the steering wheel has been operated; in a case in which operation of the right-side operation region has been detected, display a right-side image corresponding to the right-side operation region in a right-side area of a display region set in front of a driving seat; and in a case in which operation of the left-side operation region has been detected, display a left-side image corresponding to the left-side operation region in a left-side area of the display region.

In the above aspects, the vehicular display control device, the vehicular display system, the vehicle, the display method, and the non-transitory computer-readable medium storing a program according to the present disclosure enable occupant usability to be improved in configurations capable of displaying an image of an operation region.

Note that a vehicular display control device 10 is provided to the vehicle 12. The vehicular display control device 10 of the present exemplary embodiment is for example a display electronic control unit (ECU) that performs various controls.

As illustrated in FIG. 2 , the vehicular display system S is configured including the vehicular display control device 10.

The vehicular display control device 10 is configured including a central processing unit (CPU; processor) 20, read only memory (ROM) 22, random access memory (RAM) 24, storage 26, a communication interface (communication I/F) 28, and an input/output interface (input/output I/F) 30. The respective configuration elements are connected so as to be capable of communicating with one another through an internal bus 32.

The CPU 20 is a central processing unit that executes various programs and controls respective sections. Namely, the CPU 20 reads a program from the ROM 22 or the storage 26, and executes the program using the RAM 24 as a workspace. The CPU 20 also controls the respective configuration elements and performs various arithmetic processing according to the programs recorded in the ROM 22 or the storage 26.

The ROM 22 holds various programs and various data. The RAM 24 acts as a workspace to temporarily store programs or data. The storage 26 is configured by a hard disk drive (HDD) or a solid state drive (SSD), and is a non-transitory recording medium that holds various programs including an operating system, and various data. In the present exemplary embodiment, programs such as a program for performing display processing are held in the ROM 22 or the storage 26.

The communication I/F 28 is an interface enabling the vehicular display control device 10 to communicate with an external server and other equipment, and a standard such as a Controller Area Network (CAN), Ethernet (registered trademark), Long Term Evolution (LTE), Fiber Distributed Data Interface (FDDI), or Wi-Fi (registered trademark) may be employed therefor.

The first right-side operation switch 34R, the second right-side operation switch 36R, the right-side function switchover switch 38R, the first left-side operation switch 34L, the second left-side operation switch 36L, the left-side function switchover switch 38L, the first image display device 40, and the second image display device 42 are electrically connected to the input/output interface 30.

The first image display device 40 is a device for performing a predetermined display on the display region V1 of the meter display. The second image display device 42 is a device for performing a predetermined display on the display region V2 of the head-up display.

The vehicular display control device 10 is electrically connected to a driving assistance ECU 44. As an example, the driving assistance ECU 44 of the present exemplary embodiment performs control such as active cruise control (ACC) and lane tracing assist (LTA). The driving assistance ECU 44 is thereby configured so as to be capable of acquiring signals from various sensors that detect the surroundings of the vehicle 12.

The vehicular display control device 10 implements various functionality using the above-described hardware resources. Explanation follows regarding functional configuration implemented by the vehicular display control device 10, with reference to FIG. 3 .

Specifically, the right-side operation detection section 50 detects when any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R has been operated. Note that here “operation” includes not only an action by the occupant to press a switch, but also includes an action by the occupant to touch a switch. Thus, for example, the right-side operation detection section 50 detects when the occupant has touched the first right-side operation switch 34R using a signal from the corresponding static sensor. The right-side operation detection section 50 also detects when the occupant has pressed the first right-side operation switch 34R using a signal or the like from a corresponding pressure sensor.

The left-side operation detection section 52 detects when the left-side operation region has been operated. Specifically, the left-side operation detection section 52 detects when any switch out of the first left-side operation switch 34L, the second left-side operation switch 36L, or the left-side function switchover switch 38L has been operated. Thus, for example, the left-side operation detection section 52 detects when the occupant has touched the first left-side operation switch 34L using a signal from the corresponding static sensor. The left-side operation detection section 52 also detects when the occupant has pressed the first left-side operation switch 34L using a signal or the like from the corresponding pressure sensor.

In cases in operation of the right-side operation region has been detected, the operation image display section 54 displays a right-side image corresponding to the right-side operation region in a right-side area of the display region V2.

FIG. 7 illustrates a state in which the occupant is touching the upper portion of the first left-side operation switch image 34LM, and so an icon at the upper portion of the first left-side operation switch image 34LM is displayed surrounded by a circle.

There is no display performed in the left and right portions of the first left-side operation switch image 34LM. An icon for accepting the suggestion is displayed at the upper portion of the first left-side operation switch image 34LM. An icon for refusing the suggestion is displayed at the lower portion of the first left-side operation switch image 34LM.

An icon to return to the previous display is displayed in the left-side function switchover switch image 38LM. When this icon is selected, the display switches to the first left-side operation switch image 34LM, the second left-side operation switch image 36LM, and the left-side function switchover switch image 38LM in the state prior to the suggestion being displayed.

Next, explanation follows regarding operation of the present exemplary embodiment.

Explanation follows regarding an example of display processing by the vehicular display control device 10, with reference to the flowchart illustrated in FIG. 8 . The display processing is executed by the CPU 20 reading a display program from the ROM 22 or the storage 26, and deploying and executing the display program in the RAM 24.

At step S102, the CPU 20 acquires an operation situation of each of the operation regions. Specifically, the CPU 20 acquires information from the non-illustrated static sensors that are respectively installed to the first right-side operation switch 34R, the second right-side operation switch 36R, the right-side function switchover switch 38R, the first left-side operation switch 34L, the second left-side operation switch 36L, and the left-side function switchover switch 38L.

At step S104, the CPU 20 determines whether or not the hand of the occupant is contacting the right-side operation region. Specifically, in cases in which the CPU 20 has detected using the functionality of the right-side operation detection section 50 that the hand of the occupant is contacting any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R, step S104 is affirmative and processing transitions to step S106. On the other hand, in cases in which the CPU 20 has not detected using the functionality of the right-side operation detection section 50 that the hand of the occupant has contacted any switch out of the first right-side operation switch 34R, the second right-side operation switch 36R, or the right-side function switchover switch 38R, step S104 is negative and processing transitions to step S110. The processing of step S110 onward is described later.

At step S106, the CPU 20 uses the functionality of the operation image display section 54 to move the central image 60M toward the left side. At step S108, the CPU 20 causes the right-side image 62M to emerge into view in the display region V2 (see FIG. 5 ).

On the other hand, in cases in which the hand of the occupant has not contacted the right-side operation region, at step S110, the CPU 20 determines whether or not the hand of the occupant has contacted the left-side operation region. Specifically, in cases in which the CPU 20 has detected using the functionality of the left-side operation detection section 52 that the hand of the occupant is touching any switch out of the first left-side operation switch 34L, the second left-side operation switch 36L, or the left-side function switchover switch 38L, step S110 is affirmative and processing transitions to step S112. On the other hand, in cases in which the CPU 20 has not detected using the functionality of the left-side operation detection section 52 that the hand of the occupant has contacted any switch out of the first left-side operation switch 34L, the second left-side operation switch 36L, or the left-side function switchover switch 38L, step S 110 is negative and the display processing is ended.

At step S112, the CPU 20 uses the functionality of the operation image display section 54 to move the central image 60M toward the right side. At step S114, the CPU 20 causes the left-side image 64M to emerge into view in the display region V2 (see FIG. 6 ).

As described above, in the vehicular display control device 10 according to the present exemplary embodiment, the right-side image 62M corresponding to the right-side operation region is displayed in the right-side area of the display region V2 set in front of the driving seat in cases in which the right-side operation region provided on the right side of the steering wheel 16 has been operated. Similarly, the left-side image 64M corresponding to the left-side operation region is displayed in the left-side area of the display region V2 in cases in which the left-side operation region provided on the left side of the steering wheel 16 has been operated. This enables a wide area of the display region V2 to be secured compared to cases in which both the right-side image 62M and the left-side image 64M are always displayed on the display region V2.

In particular, in cases in which the display region V2 is set as a part of the windshield glass 17 as in the present exemplary embodiment, the contents of the right-side image 62M and those of the left-side image 64M can be checked in a state in which the occupant is directing their gaze toward the front while driving.

Moreover, in the present exemplary embodiment, since the right-side image 62M is displayed in the right-side area of the display region V2 whereas the left-side image 64M is displayed in the left-side area of the display region V2, the occupant can intuitively ascertain which operation region the displayed image corresponds to out of the right-side operation region or the left-side operation region.

Furthermore, in the present exemplary embodiment, since the right-side image 62M is displayed on the right side of the central image 60M whereas the left-side image 64M is displayed on the left side of the central image 60M, the occupant can even more easily ascertain which operation region the displayed image corresponds to out of the right-side operation region or the left-side operation region.

Furthermore, in the present exemplary embodiment, the central image 60M is moved when the right-side image 62M or the left-side image 64M is to be displayed, thereby enabling the corresponding right-side image 62M or left-side image 64M to be displayed in a large size, even in cases in which the display region V2 is relatively small.

Moreover, in the present exemplary embodiment, since the right-side image 62M or the left-side image 64M is displayed as an animation, the occupant can intuitively ascertain that the image (the right-side image or left-side image) displayed on the display region V2 corresponds to an operation region (the left-side operation region or right-side operation region) provided on the steering wheel 16.

Furthermore, in the present exemplary embodiment, in cases in which operation of both the right-side operation region and the left-side operation region has been detected, display of the right-side image 62M is prioritized. This enables the occupant to prioritize checking information relating to driving assistance.

Furthermore, in the present exemplary embodiment, in cases in which a suggestion from the navigation system or the like is displayed using the right-side suggestion image or the left-side suggestion image, this suggestion is displayed at a position corresponding to the pertinent operation region, thereby enabling the occupant to intuitively ascertain the position of the operation region they should operate.

Although the vehicular display system S and the vehicular display control device 10 according to the present exemplary embodiment have been described above, obviously various modifications may be implemented within a range not departing from the spirit of the present disclosure. For example, although an example of display in the display region V2 has been described in the above exemplary embodiment, there is no limitation thereto, and the corresponding right-side image or left-side image may be displayed in the display region V1.

Moreover, although a state has been illustrated and described in which the left-side suggestion image 66M is displayed by the suggestion image display section 56 as illustrated in FIG. 7 in the above exemplary embodiment, a right-side suggestion image may be displayed by the suggestion image display section 56. Specifically, the suggestion image display section 56 may display a right-side suggestion image further toward the right side than the central image 60M for an item selectable using the right-side operation region.

Furthermore, although a configuration has been illustrated and described in which the corresponding right-side image 62M or left-side image 64M emerges into view as an animation in the above exemplary embodiment, the image may also be made to retreat out of view when transitioning to a non-display state. For example, in cases in which the occupant has removed their hand from the right-side operation region while in the state illustrated in FIG. 5 , the right-side image 62M may be made to retreat out of view by the operation image display section 54 after a predetermined duration has elapsed. Namely, the operation image display section 54 may display the right-side image 62M as an animation so as to move toward the lower-right side end. Furthermore, the operation image display section 54 may move the central image 60M to the center of the display region V2 after causing the right-side image 62M to retreat out of view, or at the same time as causing the right-side image 62M to retreat out of view.

Furthermore, there is no particular limitation to the number and shapes of the respective operation switches and respective function switchover switches, which may be modified as appropriate.
